Abstract

This invention relates to a device (10) for taking at least one sample of soft tissue from an organ, said device comprising a body (11) and a needle (12) formed by a . stylet and a cannula coaxial with said stylet. The device comprises a mechanism for arming the needle, designed for sequentially moving the cannula and then the stylet from a rest position wherein the stylet and the cannula are extended towards the outside of the body, to a shooting position wherein the stylet and the cannula are retracted towards the rear of the body, and a triggering mechanism designed to release the stylet then the cannula and to allow their displacement from the shooting position to the rest position. The cannula is coupled kinematically to a cannula slider (24) comprising at least one retaining element (26) for maintaining the cannula slider in a shooting position. The stylet is coupled kinematically to a stylet slider (30) comprising at least one retaining element (32) for maintaining the stylet slider in a shooting position and means for unlocking the cannula slider. This device is characterized in that the stylet (13) comprises a sampling tip (51) able to slide into the cannula (14) and a displacement rod (42) connecting said sampling tip with the stylet slider (30), the sampling tip (51) being separate from the displacement rod (42).
